Items And Loot Archive

Ok i did the mark of intellect way back in the day before they made it a quest. but when the quest came out, i couldnt redo it, nor did i get the piece of the puzzle thing in my inventory. i have all the badges but im missing that one piece... i sent a ticket in a LONGGGGG time ago and they said it would be fixed but it has been like 6 months... anyone else have this same problem?
